3 Claims.

It has already been proposed to employ means for cooling the castingmolds of matrix composing and line casting machines, the cooling waterhaving usually been supplied to the mold-disc through the pivotal studor shaft thereof. With these constructions it was not possible to securean entirely watertight connection, and the object of the presentinvention is to overcome this disadvantage, and to provide aconstruction in which 19 the water circulation will be so arranged thatit can be kept securely watertight.

For this purpose, according to the invention, there is provided astationary ring-shaped body, preferably secured to the mold disc carrieror slide, and making watertight contact with the mold disc, the saidbody forming together with the mold disc, two annular channels whichcommunicate respectively with inlet and the outlet pipes for the coolingwater on the one hand and on the other hand, with tributory conduitsextending preferably right through the mold disc towards the castingmolds.

The accompanying drawings illustrate by way of example, oneconstructional form of the invention, and in these drawings:

Figure 1 is a vertical section through part of the mold disc, taken onthe line |I of Figure 2, and

Figure 2 is a face view of the mold disc as viewed from the left ofFigure 1, with parts at the left and right hand sides in verticalsections taken respectively on the lines .r.r and 11-31 of Figure 1.

In the drawings a is a portion of the mold slide or mold disc carrierwhich supports the pivotal stud b of the mold disc 0. The mold disccarries the casting molds d, d For purposes of cooling by water, a ringe connected to the mold slide a and to the water inlet and outlet pipesencircles the hub c of the mold disc 0. In the mold slide a, twoopenings are provided for the passage therethrough of the water supplyand outflow pipes i The pipes f and I extend into the ring e whereinthey communicate respectively with radial ports or channels g, g whichare closed at the outside of the ring by threaded plugs, and whichcommunicate respectively with annular grooves h, h in the periphery ofthe mold disc hub 0 These annular grooves h, 71 are in turn connectedrespectively to conduits 2', i extending parallelly with the mold wheelaxis in the hub c and connecting respectively with outwardly directedconduits k, k terminating behind the respective molds d, d in ports m, mThe molds themselves have each two channels 0', 0 each in opencommunication with a transverse port m, or m opening into a channel 10,extending around the respective mold slot. The cooling water is suppliedthrough the pipe 1. It runs thence through the. port g into the annulargroove h, and from there successively through the channels 2, k, m, 0',into the channel 1 passing round the respective mold slot. At the otherend of this channel p, the water flows successively through the conduitsm k i through the annular groove 11. and the radial port 9 and outthrough the channel f As the grooves h and h extend completely aroundthe mold disc hub 0 any desired number of conduits 70, 70 can branchoutwards according to the number of casting molds carried by the molddisc 0. In the example illustrated the representation is confined totwo, but obviously more or less than that number may be used. Theconduits in the mold disc 0 and in the molds (1, d are preferablyarranged as indicated in the constructional example represented, but itis obvious that instead of the channels being formed within the molddisc and the molds, pipes or the like may be used. If consideredexpedient, a plurality of adjacent conduits may be arranged around themolds to produce a greater cooling effect; in such a case these conduitsmight be arranged either behind or beside each other.

The joint between the mold disc and the ring e is made watertightpreferably by means of packing q and q In the constructional exampleillustrated the annular grooves h, 71. are formed on the periphery ofthe hub c of the mold disc. Alternatively, they could be upon thevertical face of the mold disc contacting with the front face of thering 6, or be formed partly or entirely in the ring 6.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is:

1. In a slug casting machine, the combination of a mold slide, a studfixed thereto, a mold disc rotatably mounted on the stud, said mold discbe; ing equipped with channels extending through the disc and leading toa mold, the channels communicating with separate annular grooves open atthe exterior of the mold disc, and a member in watertight contact withthe mold disc, said member being equipped near its opposite edges withwater sealing means and formed intermediate the sealing means withseparate openings in register each with one of said annular grooves andcommunicating with fixed supply and exhaust pipes, and

said member having a joint surface extending at right angles to the axisof the mold disc.

2. In a slug casting machine, the combination of a mold disc equippedwith a plurality of molds and formed with a rearwardly extending bearinghub, a mold slide, a stud fixed to the mold slide and on which the hubof the mold disc is rotatably mounted, channels formed in the mold discleading from the hub to the molds and communicating with annular groovesformed'in the cylindrical exterior surface of the hub, and a stationaryring arranged in water-tight relation to the mold disc, said ring beingequipped near its opposite edges with packing rings and formedintermediate the packing rings with passages communicating each with oneof said annular grooves and with a supply or exhaust conduit, as thecase may be.

3. In a slug casting machine, the combination of a mold disc equippedwith a plurality of slotted molds and formed with a rearwardly extendingbearing hub, a mold slide, a stud fixed to the mold slide and on whichthe hub of the mold disc is rotatably mounted, channels formed in themold disc leading from the hub to the mold and arranged for thecontinuous circulation of a cooling medium around the mold slots, a pairof noncommunicating annular grooves formed in the cylindrical exteriorsurface of the hub, and a stationary ring surrounding the hub inwater-tight relation thereto, said ring being equipped near its oppositeedges with packing rings and formed intermediate the packing rings withpassages communicating one with a supply conduit and one of the annulargrooves and the other with an exhaust conduit and the second annulargroove.
